Title :On Random Phase and Callen Approximations to Ferromagnet with Anisotropic Exchange Interaction
Authors :Matayoshi, Seitaro
Authors alternative :又吉, 清太郎
Issue Date :Sep-1978
Abstract :The random phase and Callen approximations to ferromagnet with anisotropic exhange interactions have been discussed on the basis of rigorous theory. When compared with the reslts of one and two dimensional systems, it has been found that these approximations are good in the case of isotropic and oblate anisotropic interactions but not in the case of prolate anisotropic interactions. We have also suggested improvements to the approximations mentioned above.
